The novel ‘A Long Way Down’ is not-quite-vintage Nick Hornby. And this is a disappointing film version, a bit hokey and fake. The big problem is the book’s played-for-laughs concept: four suicidal Londoners planning to top themselves on New Year’s Eve choose the same skyscraper to jump off. Pierce Brosnan out-mockneys Jamie Oliver as a disgraced daytime telly presenter fresh out of prison after a sex scandal. Imogen Poots is terrific as a sarky, brattish politician’s daughter (‘it’s exciting to have a celebrity in our suicide midst’). Aaron Paul (Jesse from ‘Breaking Bad’) is a failed rocker working as a pizza delivery guy. And, in a weird bit of casting, Toni Collette (hilarious in ‘The United States of Tara’) drabs it up as a Home Counties single mum. It’s not a spoiler to say that no one takes the plunge. There are funny moments: when the story ends up on national news, attention-seeking Poots tells a reporter how they saw an angel resembling Matt Damon on the roof. Rosamund Pike is hilarious as a bitchy TV host. But it’s hard to care about these characters. None of them is believable for a second. And the film lacks that slip-into-a-Slanket cosy feel you want from Hornby.
